Abstract
A B S T R A C T
An injection moulded plastics container with a bail handle having a projection adjacent each end, the projections extending towards each other and engaging in opposite holes in the container body wall to mount the handle pivotally therein, each projection having a cylindrical shank push-fitted in a corresponding hole, the diameter of each hole in the as-moulded state being less than the external diameter of the shank, whereby the marginal part of the body wall around the hole is inwardly deformed by the projection and is stressed under compression so as sealingly to grip the shank.

GO~r~I~ER i~lTH HANDLF
__ . __ The prest?nt invetltion relates to a container with a handle, for e~ample a con~ainer suitable for containin~
paint .
Recently, paint containers have increasingly been made of injection moulded plastics material, instead of the traditional sheet metal. It is convenient, with either sort of cont;ainer, for the container to have a yoke-like hanàle, known as a bail handle, which may be folded down when the paint container is being stored, but which may be used to lift the container, and, in particular, so that the user can conveniently hold the paint container in one hand whilst wielding a paint brush in the other.
GB 2133376 discloses an injection moulded paint container in which the two free ends of the handle are accommodated within diametrically opposed inwardly directed hollow bosses provided in the cylindrical wall of the container. The bosses are closed to the interior of the container, so there can be no leakage around the mounting points of the handle. The container, however, requires a complex injection moulding operation and is not conductive to hi~h speed manufacture of the containers.
It is well known to provide apertures through the wall of the body of a container and to mount the handle pivotally in the apertures. This is commonly used on metal buckets, but, with plastics materials, there is substantial risk of leakage of air into the container, or the contents from the container, so such constructions are not sllitable for plastics paint containers. E~a~ples are disclosed in GB 20844~8 and GB 1401039.
~'78537 Other constructions pro~-ide bosses on the exterior of the container, but these also complicate the moulding procedure and make it difficult to print the exterior surface of the container. Examp]es are shown in GB
728t73, US 392~775, US ~227623 and US 3448893.
EP 0076525 discloses an external bracket having an aperture ~hich receives a handle boss and this Quffers from the same drawbacks as the constructions with external bosses.
GB 2024309 discloses a paint container havinY a metal bod~ provided with apertures in which are push-fitted separate, resilient bosses for mountin~ the handle. This provides a very simple means of connection, but involves careful shaping of the wall at the periphery of each aperture to provide a formation to engage sealingly with the resilient boss. With plastics material, such shaping would again involve a complex injection moulding procedure.
The present invention provides a container which avoids the above problems.
In accordance with this invention there is provided an injection moulded plastics container comprising a body having a peripheral wall provided with a pair of opposite holes passing therethrough and open to the interior of the container, and a separately formed bail handle having a projection adjacent each end, the projections extending towards each other and engaging in said holes to mount the handle pivotally on the body, each projection having a cylindrical shank push-fitted in a corresponding hole, the diameter of the hole in the as-moulded state being less than than the external diameter of the shank, whereby the marginal part of the body wall around the hole is inwardly deformed by the projection and is stressed under compression so as sealingly to grip the shank.
~'78~3'7 Preferabl~, each projection includes a shoulder arouncl the shanlc at the interior of the bod~ to inhibit withdrawal of the projection from the respective hole.
Conveniently, each shank is is hollow and open at the end of the projection within the body to enhance resilience of the projection.
Advantageously, in the as-moulded state, the edge of each hole is bevelled such that the e~terior diameter of the hole is greater than the interior diameter of the hole such that the bevelled surface becomes substantially cylindrical in the stressed state. In such an arrangement, when a projection is engaged with the hole in the wall and the wall is thereby deformed inwardly at that point, the area of contact between the edge of the hole in the wall and the shank of the projection is increased, thereby providing a better seal. To proviàe an even better seal, the profile of the edge of the hole and of the portions of the shank which will be adjacent that edge may be so shaped and fit complementarily with one another and may, for example, provide a curved or even sinuous surface so as to increase further the area of contact between the ~all and the shank.
Preferably, the projection has a support portion having its surface shaped complementary to the e~terior surface of the portion of the wall surrounding ~he hole, so as to engage and support the wall in its stressed state. The provision of a support portion not only strengthens the container against the forces which will be created when the container, perhaps full of paint, is being carried, but can also provide a still greater area of contact between the wall and the proJection in order to provide an even better seal.
Reference is now made to the accompanying drawin~s wherein.-Figure 1 is a part-sectional side elevation of a container according to the invention; and .... , . ., .. ,,.. .. ,. ., .. . . . _ _ _ _ . _ _~ .. _ . ~ _ .. .. ___,. _ . _ . , .. _ __ _ _ . _ _ . _ . _ _ .. _ _ . _ _ _ . ._ . . __ _ ~ i~ure ~ is an enlarged sectional view of a portion of the container showing how a handle i~ mounted on a body of the container.
Referring to Figure 1, the container comprises an injection moulded body, e.g. of polypropylene, having a base 11 and a cylindrical wall 12. A flange 14 at the top of the body defines a drip tray and forms a rim in which a lid 13 is plug-fitted.
The wall 12 has diametrically opposite holes 2 receiving respective projections 5 on opposite end parts 4, of a bail handle 3, so as pivotally to mount the handle on the body. The handle is a one~piece plastics moulding.
Each projection 5 comprises a support portion 6 which is a block formed with a generally frusto-conical surface 15, at the apex of which is an integral cylindrical shank 7. The shank terminates at its free end in a conical head 8 definin~ an annular shoulder 9 around the shank. The head has the form of an arrow head to facilitate engagement of the projection in the corresponding hole. The shank 7 and head 8 are hollow, a bore 10 extending axially into the projection and open at the free end.
The handle is engaged with the body by forcing the projections 5 on the handle 3 into respective holes 2 in the wall 11 of the body. The head 8 of each projection ~
initially enters the respective hole 2, and the adjacent portion of the wall 11 around the hole is deformed inwardly. The projection 5 is itself resiliently deformable, the resilience being enhanced by the presence of the bore 10. Tne arrow head shape facilitates passage of the head through the hole so that the deformed portion of the wall 11 partly springs back to engage around the shank ~. The diameter of the hole in the as-moulded state is smaller than the diameter of the shank, so that the deformed portion of the wall remains deformed and ~-~'78S'~'7 stressed in compression in tight enga~ement. with the shank. The wall is held captive between the shoulder and the support portion 6.
The edge 1~ of each hole 2 in the wall 11 is bevelled in the as-moulded state t such that the hole 2 has an exterior diameter which is greater than the interior diameter. However, when the wall portion around the hole is stressed, the bevelled edge 1~ of the hole 2 becomes cylindrical to provide an increased area of close contact with the shank 7. This enhances the liquid-tight and air-tight seal formed between the handle and the body, whilst facilitatin~ pivotal movement of the handle relative to the body.
Furthermore, the geometry of the arrangement is so designed that the portion 16 of the exterior of the wall 11 surrounding the hole 2 makes a complementary fit with the generally frusto-conical surface 1~ of the support portion 6.
